SEPARABLE FASTENER.

- SPECIFICATION forming part of Letters Patent No. 615,336, datedDecember 8 Application filed January 24, 1898. Serial No. 667,759. (Nomodel.)

To all whom it may concern:

Be it known that I, GEORGE E. ADAMS, a citizen of the United States, anda resident of New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inSeparable Fasteners; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, and to theletters of reference marked thereon.

This invention relates to improvements in separable buttons or fastenerssuch as are used on garments for connecting the adjacent edges or endsof webbing or fabric.

Referring to the accompanying drawings, Figure 1 is a perspective Viewof a separable fastener embodying my present improvements, the twomembers being shown separated. Fig. 2 is a cross-sectional view with thetwo members associated. Fig. 3 is a sectional View through the socketmember alone.

Like letters of reference in the several fig ures indicate the sameparts.

The letter A indicates the stud member, which is preferably struck upfrom an integral piece of metal and is provided with a transverse cut a,so as to render the stud elastic in cross-section and adapted to enteran aperture which is smaller in diameter than the maximum diameter ofthe head. The

.fiange A of the stud member is preferably provided with apertures a, bymeans of which it may be fastened to the goods or garment, the edges ofwhich are to be united.

The letter 13 indicates the socket member, which in this instance isalso struck up from sheet metal and is in the form of an annulus, whichwill not yield when the stud member is inserted therein. This socketmember is provided with a surrounding base-flange 1), preferablyscalloped, as shown, and adapted to be secured to the face of thegarment or fabric by threads or' stitches passed through apertures 17 insaidflange b. Extending upwardly from the flat base-flange is a dome orprojection having a side wall C and a top portion 0, provided with acentral aperture C constituting the rigid entrance-opening for the studof the member A. The general plane the entrance-aperture.

of the top of the dome or projection is parallel with the plane of thebase-flange but said top C is corrugated concentrically with the centralentrance-opening, thereby not only strengthening the plate, but insuringa bearing of the base-flange A of the stud member remote from the edgeof the central opening, and thereby preventing the stud from rocking outof engagement when lateral draft is applied.

By reference to Fig. 2 it will be seen that the relative positions ofthe parts when the two members are brought together is well illustrated,the substantially flat base-flange of the stud member contacting ortaking a bearing on the top of the dome at the outer edge of the latteror at a point remote from It will be further seen from Figs. 2 and 3that the edge of the entrance-aperture with which the neck of the studcooperates to resist lateral strain is not depressed to any appreciableextent below the general level of the top of the dome, or, in otherwords, the Whole top of the dome, including the holding edge, is in thesame general plane.

This construction of fastener has been found to be exceedingly efficientand cheap to manufacture. There is little or no danger of the partsbecoming separated through lateral draft, andby forming the projectionin the socket member in the manner stated achamber or recess for thehead of the stud member is formed above the plane of the goods to whichthe socket member is applied.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a separable fastener, the combination with the stud member havinga substantially fiat base-flange, of a socket member with asubstantially fiat base-flange having apertures adapting it to besecured to the top surface of the garment, and a central dome orprojection having a central entrance-aperture formed therein, the top ofthe dome or projection being extended around the entrance-aperture in aplane parallel with the base-flange whereby the outer edge of the domeis at substantially the level of the entrance-aperture and formsabearing for the flange of the stud member remote from theentrance-aperture; substantially as described.

2. A socket member for separable'fasteners With a base-flange adapted torest on the top surface of the garment and. provided. With apertures forthe attachment of the member, a central annular projection having acentral aperture with its holding edge in substan- Io tially the planeof the top of the projection,

the top of the projection lying in a plane parallel with the base-flangeand being formed into a series of annular ribs constituting bearingsaround the holding edge of the aperture; substantially as described.
